...yes, lots of things, and all of them a mystery to the thousands of tiny nomes living under the floorboards of a large department store, most of whom have never even set eyes upon the outside world. Things like Day and Night and Sun and Rain don't really exist, say all intelligent nomes. They're just daft old legends.

But soon a devestating piece of news is to shatter the nomes' existence: the Store - their world - is to be demolished...

So it's up to Masklin, the last nome to come into the Store, to mastermind the unbelievable escape plan that will take all the nomes into the dangers of the great Outside.

It means they have to think. And they have to think BIG.

And they start to learn who they are and how they came to be there, and where their fantastic journey must one day take them.
